HELP ADVICE PLS... period 1 day after ovulation...???

Hey ladies I’m TTC and have been tracking my periods for about 6 months and only started using ovulation test the last 2 months... as per a positive O test 2 days ago, Ovulation was yesterday and today I have what seems like heaving spotting, I’ve gone through 3 thick panty liners through the day....? Initially this morning I saw spotting so I googled it and started seeing that spotting can occur 4-7 seven days after O which is referred to as implantation bleeding so I started to get a tad excited but it’s only 1 day after O so I’m just really confused and worried it could mean pregnancy isn’t possible...

Any advise would be greatly appreciated. Thanks from a very confused TTC woman.
